Ultimaker CPE+ (Co-Polyester Plus) in Transparent is an engineering-grade filament that combines the chemical resistance, low moisture absorption and dimensional stability of CPE+ with a translucent appearance. Available in the native 2.85mm Ultimaker diameter on a 700g spool, it opens up a unique set of applications where both material performance and visual clarity are required in the same part.

Transparent CPE+ is ideal for inspection windows in fluid systems, light diffusers, safety guards, liquid containers and visual prototypes where the internal structure or contents need to be visible. The translucency also aids prototype review and design validation by making wall thickness and internal geometry easier to assess without cross-sectioning the part.

Key features

• Translucent finish for inspection windows, light guides, display covers and visual functional prototypes.
• Excellent chemical resistance to oils, fuels and many solvents - suitable for fluid-contact applications.
• Low moisture absorption for stable mechanical properties and consistent printing performance.
• 2.85mm diameter, 700g spool with NFC chip for automatic Ultimaker material recognition.
• Low warping and good dimensional stability for accurate, repeatable part production.
• Also available in Black (professional, opaque) and White for applications requiring different colour coding.

Compatible with: Ultimaker S-series, Ultimaker 3 (ext), Ultimaker 2+ (with CPE+ profile)

In the box: 1 x Ultimaker CPE+ Transparent 2.85mm 700g spool
